RAILWAY-TRAOK CONSTRUCTION.

Specification of Letters Patent,

Application filed March 25, 1910. Serial No. 551,428.

T all whom it may concern:

Be it known that I, LoUIs H. Evans, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Track Constructions, of which the following is a specification.

This invention relates to railway track constructions, and more particularly to a 'concrete construction provided with short wooden blocks for supporting the track rails, Wl11Cl1 afford all of the advantages of an ordinary wooden tle, and at the same time produce a structure which is cheap to manu facture and possesses great durabillty.

It is an object of this invention to provide a construction in which the rail supporting blocks can be readily removed and replaced when occasion requires, and in which the blocks willb'e' securely and firmly retained in position and prevented from accidental displacement.

Another object of this invention is the provision of a track construction which is elevatedbetween the track rails to serve as guardrails, thus obviating the necessity of providing the track with the additional guard-rails usually employed. 'Further'objects and advantages of my invention will become apparent to those skilled in the art, as it is betterunderstood by reference to the following description when taken in connection with the accompanying'drawings illustrating a preferred embodiment thereof.

Referring to the drawings-Figure 1 is a section on the line 11 of Fig. 2, and, Fig. 2 is a" plan view of a preferred embodiment. Referring to the drawings, 3 designates generally, the concrete bed orfoundation of the track, which may be reinforced, if de sired, in anypreferred manner. The concrete foundation is raised between the track rails as at 4, to a plane'substantially flush withthe top of the track rail, and the sides of the raised portion are reinforced and protected by suitable Z-bars 5, which are securely fixed to the concrete structure by means of bent retaining rods 6.

7 represents suitable wooden supporting blocks located in the concrete bed and composed of two pieces, 8 and 9. The recesses'in which these blocks are located are preferably rectangular in shape and the inner ends t-hereof extend into the center'portion of the concrete construction, providing a pocket,

the upper wall of which is substantially 11 which extend through the lower wing of the Z-bars '5, the blocks -9, and 'into the blocks 8, as shown. The blocks may be further fastened together by screw-spikes '12 located near the outer ends of the blocks. The track rails 13 are fastened upon the blocks in the usual. manner by means of,

spikes or screws 14:, and tie-plates 15 may be interposed between the rails and the sup porting blocks, if preferred, although the use of tie-plates is not essent-ial'to the success of my invention. f

In constructing a track bed of this character, the blocks 8 and 9, which are substantially rectangular inshape, as shown Patented July 5, 1910.

to the left in Fig. 1, are properly positioned, V I

and the concrete is filled in around them, the Z-bars forming the side walls of'the raised central portion of the construction,

and theretaining rods serving to securely maintain the bars in position when the concrete sets. The concrete in plastic condition is molded around the supporting blocks to form the bevel-beads 10, and the portion thereof outside the ends of'the' block is made lower than the top of the lower block 8.

hen it becomes necessary to' repair the track, by replacing the supporting blocks,

the spikes or screws 11, 12, and let are removed,which frees the upper block 9 from the block 8. The 'upper'block maynow be it withdrawn longitudinally from the recess, whereupon the block 8 may be removed. The new block 8, which is to replace theold block 8 which has been removed, is beveled off at 16 as shown atthe right in Fig.1, so that the block can be placed in position. The necessity of beveling off the end of the block is obvious, from .the'fact that the block can not be slid longitudinally into place, but the inner end must firstbe in-" 20 ing a concrete bed provided with sorted into the recessed pocket, and the i outer end subsequently lowered into vposition. The block 9 may now-be inserted longitudinally into the recess from-the outer end thereof, whereupon the screw-spikes maybe replaced to hold the blocks together and in position, andsecure the rails thereto. The initial cost of track constructlon emv bodying my invention, is relatively small," '1 and the structure'is' very durable, thereby greatly reducing the usual f cost of maintenance. When it becomes necessary to replace the supporting blocks the old ones can be readily. removed andthe new ones quickly placed inposition, whereby the question of track repairs resolves itself into a ,simple and 1nexpens1ve..1tem.

A railway track construction, compris I p a recess dlsposed transversely to the track, and a block having upper and lower sections dis-j 'posed in'said recess, the outer end wall of the recess being of a height sufficient to pre- 5 vent longitudinaldisplacement of thelower block section, but permitting the upper block section to be withdrawn horizontally from the recess.

V o 2. In a. railway track construction, the combination of a concrete bedprovided with a rectangular recess disposed transversely to" the track, a removable block seatedin said i reces's, means for securing said block at its the concrete structure, and a track rall supported on said block.
